Application filed February 16, 1914. Serial No. 818,860.

T 0 all whom it may concern: 1 i 1 Be it known that I, Gnoaor A. WEBSTER, of Somerville, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and use ful Improvement in Brake-Handles, of

which" the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of provide a brake handle of relatively few parts cooperating with one another to pro vide a handle of superior strength and elliciency and one moreover absolutely positive in itsoperation. I

My invention can best be seen and under-- stood by reference to the drawings in which. there is shown an embodiment thereof and in whichas they are elements commonly employed.

Secured to the brake rod is a clutch menu her 2 the upperedge of which is provided with a circular row of clutch teeth 3. This clutch member connects with the brake rod by the formation-therein of a socket l'into which the end of the rod extends, the menu her being then fixed to therod by a crosspin 5. Extending upwardly from the clutch member 2 and preferably integral there with is a central post 6. This post is in line with the brake rod and may be considereo substantially acontinuation of the rod. Ar-

.ranged upon the upper end of this post is a collar? having formed therein an annulargroove 8. Mounted upon the post is a cluunhered casing 9. This casing is secured to the post in a manner whereby it may rotate but without endwisedisplacement For this purpose the head'ofthe casing is pro yided on the interior with a socket or opent [nihilism i.) m.-.

r 1h 10 into which the end of the post and secured by means of a key 11 which passes through the head of the casing and 15 con collar thereon extend, the casing being then tained to lie in part within the annular recess 8 formed inthe collar as aforesaid. By

this means of attachment the casing is mounted to rotate but held fixedly as against endwise displacement.

The casing 6 extends downwardly; and the bottom end 12 thereof fits snugly around the outer surface of the clutch member 2, thereby closing the interior of thecasing.

Arranged within the casing and around the post'G is a movable clutch, member 13. Upon the bottom edge thereof this member is provided with an annular row of clutch teeth 14: by which the two clutchmembers may cotiperate to have operative engagement with one another in the usual manner. For this purpose the movable clutch member has both a rotary and an end+ wise movement, a rotary movement in order that it may be rotated or turned to have an intermittent engagement with the fixed clutch member 2 and a sliding endwise movement not only to secure this eifcct but also to enable its being raised into a disengaging position with relation to the member 2 and adjacent parts. The movable clutch member rotates with the rotary casing 9 and is also mounted to slide cudwise therein. For this purpose the interior of the casing is provided with channels or angular grooves 15 in which the movable clutch member is mounted to slide, the same being squared or otherwise augularly formed by parts 16 so as to fit and slide longitudinally within grooves 15 of the casing.

On the interior thereof the movable clutch member 1s provided with an annular flange or edge 17 whioh'fits around the post (3. Betweenthis flange or edge and the collar 7 on the top end of the post is arrangml a compression spring 18 the tension of which operates to hold the movable clutch member in a normal engaging position. The spring 17 is coiled around the post and is otherwise retained by an annular extension 19 to the movable clutch member providing a housing for the spring. Upon the exterior thereof the movable clutch member 13 is provided with an annular socket or opening 20 presenting a top annular edge or shouling.

der :ll. Formed in the diametrically-opposite sides of the casing 9 are sockets or openings These openings are adjacent the opening it) in the movable clutch member 13 and provide hearings in the casing for the ends of the drop lever 2st. The drop lever 24-, comprises a handle 25 from which eX- tend forked arms 26 around the opposite sides of the casing and carrying upon their respective c-nd's circulan butts 2T socketed to turn avithin the openings 23 of the cas- Attachment is secured between the arms 26 and these butts by squared heads 28 projecting from the outer faces of the re spective hutts andwith which therespective arms'QG connect. Projecting from the inner faces of each of the respective butts are studs 30 ecccntrically arranged with relation to the center of the butts 27 and which project into 1e opening 20 in the movable clutch member beneath its top edge or shoulder 2].. Thus supported upon the casing 9, the drop lever may be turned from a position, where its handle projects outwardly with a substantially horizontal projection at right angles to the axis of the casing and movable clutch member, to a dropped position where the handle will'lie substantially parallel with said axis and also the brake rod as is customary in such types of lovers. In this connection it is to be observed that the arms 26 of the lever are preferably bent arms in order that the lever may be dropped without interference with the casing.

The disposition and arrangement of the operating parts of the'lever, especially with reference to the studs 30, which form practically parts of the lever, are such that when the lever is occupying its out-turned posi tion. the studs 30 will be contained to lie in the opening 2Ov of the movable clutch member just below the edge 21 thereof without engagement with this edge. When; however, the lever is dropped these studs ow ng to the eccentricity thereof and operating essentially as arms to the lever, will engage the edge 21 of the movable clutch member and lift this member into a disengaging'posit-ion with relation to the member 2, the spring 18 beingthen compressed and the movable clutch member sliding within the casing.- v v The further operation of the parts is as follows: The respective clutch members .00-

operate with one another for turning the brake rod and setting up the brake in the usual manner, the movable member having an intermittent forward and reverse" rotary movement engaging the teeth of its complementarv member during the forward movement thereof and. riding backwardly over the same for a fresh. grip upon the reverse m'ovem'e'nt thereof. The rotation of the movable clutch member for,,setting up the brake is obtained through the rotation of the casing 9 by the lever when in its outturned or horizontal position. During this operation the studs 30 carried by the lever will occupy positions out of engagement with the edge 21 of the movable clutch member, permitting this member to have proper freedom to operate. \Vhen, however, the lever is dropped it will fulcrum upon the casing and the studs 30 thereof operating as lifting fingers or arms of the lever, will engage the edge 21 of the movable clutch member and by their bearing against this edge will lift the movable clutch member into a disengaging position with relation to its complementary member and maintain it in such disengaging position as long as the lever is maintained in adropped position.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.'
